- *
- * - Figure out what to do if a puzzle requests a size bigger than
- * the screen will take. In principle we could put scrollbars in
- * the window, although that would be pretty horrid. Another
- * option is to detect in advance that this will be a problem -
- * we can probably tell this using midend_size() before actually
- * generating the puzzle - and simply refuse to do it.

+ * These argument-breaking rules apply to Visual Studio 7, which

+ * port of my puzzles. Visual Studio 10 has different rules,
+ * lacking the curious mod 3 behaviour of consecutive quotes
+ * described below; I presume they fixed a bug. As and when we
+ * migrate to a newer compiler, we'll have to adjust this to
+ * match; however, for the moment we faithfully imitate in our GUI
+ * utilities what our CLI utilities can't be prevented from doing.
+ *
+ * When I investigated this, at first glance the rules appeared to
+ * be:
+ *
+ * - Single quotes are not special characters.
+ *
+ * - Double quotes are removed, but within them spaces cease
+ * to be special.
+ *
+ * - Backslashes are _only_ special when a sequence of them
+ * appear just before a double quote. In this situation,
+ * they are treated like C backslashes: so \" just gives a
+ * literal quote, \\" gives a literal backslash and then
+ * opens or closes a double-quoted segment, \\\" gives a
+ * literal backslash and then a literal quote, \\\\" gives
+ * two literal backslashes and then opens/closes a
+ * double-quoted segment, and so forth. Note that this
+ * behaviour is identical inside and outside double quotes.
+ *
+ * - Two successive double quotes become one literal double
+ * quote, but only _inside_ a double-quoted segment.
+ * Outside, they just form an empty double-quoted segment
+ * (which may cause an empty argument word).
+ *
+ * - That only leaves the interesting question of what happens
+ * when one or more backslashes precedes two or more double
+ * quotes, starting inside a double-quoted string. And the
+ * answer to that appears somewhat bizarre. Here I tabulate
+ * number of backslashes (across the top) against number of
+ * quotes (down the left), and indicate how many backslashes
+ * are output, how many quotes are output, and whether a
+ * quoted segment is open at the end of the sequence:
+ *
+ * backslashes
+ *
+ * 0 1 2 3 4
+ *
+ * 0 0,0,y | 1,0,y 2,0,y 3,0,y 4,0,y

+ * u 3 0,1,y | 0,2,n 1,1,y 1,2,n 2,1,y
+ * o 4 0,1,n | 0,2,y 1,1,n 1,2,y 2,1,n
+ * t 5 0,2,n | 0,2,n 1,2,n 1,2,n 2,2,n
+ * e 6 0,2,y | 0,3,n 1,2,y 1,3,n 2,2,y

+ *
+ * There is very weird mod-3 behaviour going on here in the
+ * number of quotes, and it even applies when there aren't any
+ * backslashes! How ghastly.
+ *
+ * With a bit of thought, this extremely odd diagram suddenly
+ * coalesced itself into a coherent, if still ghastly, model of
+ * how things work:
+ *
+ * - As before, backslashes are only special when one or more
+ * of them appear contiguously before at least one double
+ * quote. In this situation the backslashes do exactly what
+ * you'd expect: each one quotes the next thing in front of
+ * it, so you end up with n/2 literal backslashes (if n is
+ * even) or (n-1)/2 literal backslashes and a literal quote
+ * (if n is odd). In the latter case the double quote
+ * character right after the backslashes is used up.
+ *
+ * - After that, any remaining double quotes are processed. A
+ * string of contiguous unescaped double quotes has a mod-3
+ * behaviour:
+ *
+ * * inside a quoted segment, a quote ends the segment.
+ * * _immediately_ after ending a quoted segment, a quote
+ * simply produces a literal quote.
+ * * otherwise, outside a quoted segment, a quote begins a
+ * quoted segment.
+ *
+ * So, for example, if we started inside a quoted segment
+ * then two contiguous quotes would close the segment and
+ * produce a literal quote; three would close the segment,
+ * produce a literal quote, and open a new segment. If we
+ * started outside a quoted segment, then two contiguous
+ * quotes would open and then close a segment, producing no
+ * output (but potentially creating a zero-length argument);
+ * but three quotes would open and close a segment and then
+ * produce a literal quote.
